PHONOGRAPH ATTACHMENT.

Application filed April 21, 1924. Serial No. 707,950.

This invention relates to new and useful improvements in attachments for phonographs and more particularly adapted to a device which is removably associated with the sound reproducer of the phonograph.

One of the important objects of the present invention is to provide an attachment in connection with the sound reproducer of a phonograph whereby a tone modifier and diaphragm protector is provided.

A still further object is to provide an attachment of the above mentioned character, which includes a means for supporting a cleaning member for cooperation with the needle for cleaning the record while the same is being played.

A further object is to provide an attachment of the above mentioned character, wherein the cleaning member may be positioned in such a manner as to render the same operative for use in connection with records which are provided with either a lateral or vertical groove.

A still further object is to provide a sound reproducer attachment of the above mentioned character, which is simple in construction, inexpensive, strong and durable and furthermore adapted for the purposes for which it is designated.

Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals designate like parts throughout the same Figure 1 is a side elevation of a sound reproducer showingmy attachment in position thereon, and

Figure 2 is a detail perspective view of my attachment.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates a sound reproducer which is of the usual construction and is supported on the forward end of the tone arm 2 in the usual manner. Associated with the sound reproducer 1 is the usual diaphragm vibrating bar 3 on the outer end of which is supported the needle 4 in the manner well known in the art. As the above elements do not form any important part of the present invention, it is not thought necessary to further go in detail relative to the same.

My attachment compri es a ub tan l y illustrated in Figure 1.

circular member 5 which is formed of any suitable elastic material preferably rubber and the same is of such size as to have the fiat inner face thereof fitting snugly within the marginal rim of the sound reproducer 1 and against the diaphragm supported therein. The resilient member 5 is adapted to be frictionally supported in the sound reproducer and formed in the fiat face thereof is the radially extendin channel or groove 6, the purpose of which 1s to provide a means for receiving the outwardly extendmg portion of the bar 3 in the manner as clearly illustrated in the drawing. The purpose of the provision of the resilient memher 5 will hereinafter be more fully described.

Extending downwardly from the resilient member 5 is the metallic rod 7, the upper end of which is bent as shown at8and supported in the central portion of the resil- 1ent body member 5 in the manner clearly The outer end of the metallic rod 7 is disposed laterally at substantially right angles to the downwardly extending portion as illustrated at 9 in the drawing. The lateral extension 9 terminates in a right angular extension 10 and these extensions provide a means forreceiving the cleaning member indicated generally by the numeral 11 .and the latter is formed preferably of felt, although any other suitable material may be used for the purposes for which the same is designated.

The provision of the resilient body member 5 in the sound reproducer member 1 forms a means for modifying the tone so that the phonograph will play the records in such a manner as to render the sounds clear, thus removing the harshness and the mechanical sound from the music which is being played. The resilient member 5 further acts as a protector for the diaphragm for the sound reproducer when the same is in position thereon.

To prevent the accumulation of dust or dirt on the record, the felt pad or cleaner 11 is provided and the same 1s disposed rearwardly of the needle 4 and is adapted to travel over the record together with the movement of the needle and the sound reproducer carrying the same so that .the felt cleaner will remove all of the dirt or dust which has accumulated on the record while the latter is being played. The provision of the teral ext nsi n 9 and the right angular extension 10 provides a means whereby the cleaner may be used in connection with rec rds which are provided either with lateral grooves or a vertical groove depending on the character of the record being played and the positioning of the sound reproducer. An attachment of this character may be easily and readily placed in position on the sound reproducer of a phonograph and W111 not in any way interfere with the operation thereof. The simplicity of my device enables the same to be manufactured at a very low cost and the parts are further so arranged as to be strong and durable.

\Vhile I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to Without departing from the spirit of the invention and the scopeof the appended claims.

Having thus described the invention, what- I claim is 1. An attachment for a reproducer comrising a comparatively heavy flat faced body of circular form, said body being comosed of yieldable material and being of a diameter to fit snugly within the rim of the reproducer while permitting the flat face thereof to contact the outer surface of the diaphragm of said reproducer, said body being provided in the flat face with a radially disposed groove extending from the center and opening through the peripheral edge in order to receive and accommodate a portion of the diaphragm vibrating bar of the reproducer.

2. An attachment for a reproducer-comrising a comparatively heavy fiat faced body of circular form, said body being composed of yieldable material and being of a diameter to fitsnugly within the rim of the reproducer while permitting the flat face thereof to contact the outer surface of the diaphragm of said reproducer, said body being prov ded in the flat face with a radially disposed groove extending from the center and opening through the peripheral edge in order to receive and accommodate a portion of the diaphragm vibrating bar of the reproducer, and a hanger rod connected to and depending from the peripheral portion of said body and extending below said portion, the lower end of said bar being fashioned to permit a record cleaning device to be hung thereon.

3. An attachment for a reproducer comprising a flat faced circular body of a diameter to fit snugly within the rim of the reproducer, said body being com osed of yieldable material and being provi ed in its flat face with a groove extending from the center and through the periphery to accommediate a portion of a stylus bar, a hanger rod embedded in said body and extending in substantial parallelism with said groove through the periphery of the body and beyond said periphery, the extended portion being bent to provide a right angular part, on the portions of which a record cleaning device may be selectively suspended.

4. An attachment for a reproducer comprising a rod, one end of which is bent to provide a right angular part, a pad folded upon itself at a point between its ends and adapted to be selectively hung over the portions of said right angular part, and means connected to the opposite end of the rod for connecting the same with the rim of said reproducer. a

In testimony whereof I affix my signature. FRANK L.- FORTUNE.
